Hey,

I’m using snmp-scan.php to add servers to LibreNMS every day using a cron job. The downside is that we don’t know if a server was added or removed. Is it possible to add a feature or tweak an option to get more information about the process?

Unfortunately, this doesn’t mean much to us:

Range: 10.16.160.0/24

-*..*.*.............**....******.......*............................................................*.........**..............................................................................................................................................

Scanned 254 IPs, Already known 15 Devices, Added 0 Devices, Failed to add 1 Devices.

You can add the -d for debug info

Thanks for the tip, it’s helpful but still not as good as making my own wrapper over the API to get some normal output that can be helpful for troubleshooting and reporting.

Also, FYI, snmp-scan.PHP cannot remove devices.

Thanks, I wasn’t sure.
